We aimed to investigate associations between dietary macronutrient proportions and prospective visceral adiposity index changes (VAI). The study included 1254 adults (18-74 years), from the Tehran Lipid and Glucose Study (TLGS), who were followed for three years. Dietary intakes were assessed twice using food frequency questionnaires. Associations of dietary macronutrient with VAI and risk of visceral adiposity dysVAD) after three years were investigated. The percentage of energy intake from protein in the total population, and from fat in women, were associated with higher increases in VAI. A 5% higher energy intake from protein substituted for carbohydrate, monounsaturated fatty acids (MUFAs), and polyunsaturated fatty acids (PUFAs) was associated with higher VAI. Higher energy intake from animal protein substituted for PUFAs was positively associated with VAI. Substituting protein and PUFAs with MUFAs were related to higher VAI. The associations were similar in men and women, but reached significance mostly among women. Risk of VAD was increased when 1% of energy from protein was replaced with MUFAs. Substituting protein for carbohydrate and fat, and fat for carbohydrate, resulted in increased risk of VAD in women. Higher dietary proportions of protein and animal-derived MUFA may be positively associated with VAI and risk of VAD.
